At her eighteenth birthday banquet, a blood-red countdown appears out of nowhere: [72:00:00]. A cold voice announces that when time runs out, her secret, that she is a woman disguised as a man, will be exposed to the world. The crime of deceiving the emperor carries a sentence of execution for her entire family.
In this desperate situation, Su Yunqing discovers that the only person who can pause the deadly countdown is her sworn enemy, Xiao Jue, heir to the Duke of Zhenguo. To survive, the once aloof top scholar must set aside her pride and awkwardly cling to the man she hates most.
At court, she pretends to faint and falls into his arms. Inside the imperial carriage, she “accidentally” brushes his fingertips. Xiao Jue pulls away and warns her with a cold laugh: “Scholar Su, please behave yourself!”
He thinks she has ulterior motives, unaware that every touch is a chance she has stolen from the Grim Reaper. She thinks he is merely an antidote, never realizing that their fates have long been intertwined through their repeated brushes with life and death.
When the truth behind the countdown is revealed, it turns out to be part of a shocking conspiracy that threatens the very foundations of the state. Can Su Yunqing protect her family and break free from her fate amid one deadly trap after another? And when will the heir, who keeps insisting he has “no interest in men,” discover the greatest secret of the person beside him in bed...
